System availability

Check current server status and planned outages before beginning the filing process. Eastern Time controls for purposes of determining whether your TEAS filing was timely filed. Any submission that arrives as of 11:59 p.m. Eastern Time will be given that day's filing date regardless of the USPTO's regular business hours. If you have a filing due today and the document cannot be filed via TEAS, you must use an alternative method of filing to ensure that the document is timely received by the USPTO.

Upload schedule

Most filings made through TEAS are uploaded into the USPTO's Trademark Status and Document Retrieval (TSDR) system within four to five business days. If that amount of time has passed and your filing is still not appearing, please email TSDR@uspto.gov. However, if the problem specifically relates to an electronic filing issue, email TEAS@uspto.gov.
